Thanks for the link, I actually spent way too much time looking at that already :)
When I first put the CPVC manifold together, it looked pretty good, but after a couple of reassembles, I think either I have the pieces mixed up, or I was off to start with. There's two arms now, and a big space in the middle. I made sure to keep the arms the suggested distance from the edges of the MLT, but I want to put another arm in the middle.
I've given thoughts to the false bottom, but it's a rectangular shaped bottom, and I was concerned with channeling. I think I'm going to put the additional arm in, and try to see where my efficiency is.
BTW, I followed the link in your signature for
www.cornelsbrewing.com, and all of the picture links are broken.

50% is bad, but not for your first few brews. I was barely hitting 60% ten AG brews in. After you get the feel for your system, and you learn all the variables, you should be fine. I'm still only hitting around 75% on my system, but I'm happy with that for now. Grain crush has a big impact on your gravity too, so if you're crushing at the LHBS, double or triple crush your grains.
Also, how did you manage to brew a beer .056 higher than the recipe? That's huge!

Ha! Sorry, that's a typo. I was .006 higher. Man, that would be huge!
The way I'm calculating it is by figuring out the max available gravity points from this chart:
http://www.homebrewtalk.com/wiki/index.php/Malts_Chart
Calculating each grain's points by the number of pounds, then adding that up, and dividing the total by the number of gallons I collected. That should be giving me the max gravity.
Then I take my gravity reading, and divide it by the max gravity.
I am crushing the grain at the LHBS, and I will definitely have to try double or triple crushing it next time.
Thanks for the help guys!
